Hi All,
i am new ruby on rails n i am currently working on xml with Ruby on
rails.
i prepared string and passed that string into simplexml module
xml_data = "<records>
<record><first>1</first><second>2</second><third>3</third></record>
<arn><child1>First</child1><child2>Second</child2><child3>Third</child3></arn>
<arn><child1>First</child1><child2>Second</child2><child3>Third</child3></arn>
<arn><child1>First</child1><child2>Second</child2><child3>Third</child3></arn>
</records>"
data = XmlSimple.xml_in(xml_data)
i got pure xml now and converting that xml into model object and when i
am trying to save the object it is inserting with the junk values as
shown below
'---- "1"', '--- - "2"', '--- - "3"', '--- - First', '--- - Second',
'--- - third'

Problems with Rails and/or ActiveRecord would best be asked on a Rails
mailing list (here you have found the general Ruby programming language
list)
From a Ruby point of view, I'd suggest you try using 'inspect' on your
model before saving it. e.g.
# create your model
foo = Foo.new(...)
# show it
STDERR.puts foo.inspect
foo.save!
This divides your problem in half: if @attributes contains the right
data then the problem is when ActiveRecord saves it, but if @attributes
contains the bad data then you can work on the first part of your
program.
'---- "1"', '--- - "2"', '--- - "3"', '--- - First', '--- - Second',
'--- - third'
Strange, looks like it's converting to YAML for some reason.

Sir,
when i add the Code what you gave like STDERR.puts foo.inspect
it printed like this, i think this is correct data.
#<XMLDemo first: ["1"], second: ["2"], third: ["3"], child1: ["First"],
child2: ["Second"], child3: ["Third"], id: nil>
But still i am facing the same problem. plz help to solve this prb
Thanks in Advance

No, that's wrong, and it explains why your data is getting serialized as
YAML.
Each of your attributes is an array:
["1"]
when it should be just a string
"1"
XmlSimple is giving you an array because you might get multiple elements
with the same name:
<record>
<first>foo</first>
<first>bar</first>
<first>baz</first>
...
</record>
So your code which copies from your XML structure into your ActiveRecord
model needs changing, e.g. by using .first or [0] to pick the first
array element.
I have a vague recollection that there's an option you can pass to
XmlSimple for it *not* to put elements inside arrays; look through the
docs.

You are correct. I just had similar problem as OT.
The option is 'ForceArray' => false
